Ah, the recent incident with China's space station has really entangled people! I heard that the altitude of the space station has been "falling off the horse", and I wonder if it will fall to the earth. I'm afraid in my heart, I'm afraid of smashing everyone! I heard that the main cause was the geomagnetic storm caused by solar activity. Alas, space is really full of unknowns, so let's learn a little about the sun and geomagnetic storms.
What the hell is a geomagnetic storm? Hear me clearly, as the name suggests, the earth's magnetic field has been violently disturbed. You see, the earth is like a super-large magnet, enveloped in a "magnetic field" in all directions. But once the sun is "crazy", it will "eject" a large number of high-energy particles or something, and directly "hammer" the geomagnetic field, stirring up the magnetic field into a mess, and people call it a geomagnetic storm.
Don't look at the small geomagnetic storm, in fact, there are all levels. Some even have a shadow at all, just like the aunt next door; But it is also a little too "facing the sky", what satellites and spacecraft are not bombarded by it, and even human health will be affected. I heard that when a geomagnetic storm comes, you can see the colorful aurora in the sky a little closer to the earth, which is really beautiful!
But for spacecraft flying in space, geomagnetic storms can be their big nemesis. Although the Earth's "atmosphere" is still a shield, those spacecraft that are too close to the Earth will not escape. For example, China's space station flies in low-earth orbit, and once a geomagnetic storm hits, don't say anything, just "drag" its altitude down.
This time, the height of China's space station is indeed the fault of geomagnetic storms. I heard that on May 11th, it descended as much as 1 kilometer, which scared people! The bigwigs of the space center came out to "stabilize" everyone, saying that the astronauts were safe and sound. He also said that China's space station has protective measures, and resisting geomagnetic storms is not a "big job" at all.
In the future, China's space station will continue to train its "immunity" to the "weather" and build a safer home for astronauts. In other words, through this episode of the space station, haven't you realized how "discriminatory" the space environment is for human beings? If you want to further "expand your territory" in the future, you must study new technologies and always fight against the "unreasonable" changes in space.
I see, it's not a big deal. The key is to arouse everyone's enthusiasm for space exploration, so that everyone can "keep an eye on" the "conspirators" of the sun and geomagnetic storms! Who doesn't know the brave spirit of our Chinese astronauts? Just by relying on this small geomagnetic storm, I want to "block" the take-off of China's aerospace industry, but there is no door!
I am confident that the Chinese space station will definitely be able to withstand this "catastrophe". In the future, we will continue to make breakthroughs in the construction and operation of the space station and perform more "unique activities", such as "pressing" the geomagnetic storm on the surface of the earth and letting it "rest"! At that time, the bright starry sky will completely become our "back garden"!
